This invention relates to means to support a window shade between the jambs of a window frame and particularly to means adjustably and removably clamped between the jambs without requiring the use of fastening means entering the jambs.

It is the principal object of the invention to provide means to support window shades having a minimum number of parts, and which is secured between the jambs of a window frame in window shade supporting position and removed from the window frame by actuating only one of said parts.

It is another object of the invention to provide window shade supporting means which is readily assembled and taken apart for storing or shipping.

It is a further object of the invention to provide window shade supporting means which is simple in structure and inexpensive to manufacture.

A further object of the invention is to provide shade supporting means which does not mar the window frame and is most suitable for metallic window frames, as it does not require the use of fastening means entering the frames.

Further objects of the invention will be set forth in the detail description of the invention.

In the drawing accompanying and forming a part of this application Figure 1 is a view of window shade supporting means constituting the embodiment of the present invention positioned between the upper ends of the jambs of a window frame before it is secured between the jambs.

Figure 2 is a view similar to Figure 1 showing the window shade supporting means actuated to window shade supporting position between the window frame jambs and a pair of shades supported by said means.

Figure 3 is a view, on an enlarged scale, of a clamping plate of the shade supporting means looking in the direction of the. arrows from the line 3-3 of Figure 2 and showing in cross section flat studs of the window shades and an adjusting member of the supporting means engaged in said plate.

Figure 4 is a sectional view taken on the line 44 of Figure 3 looking in the direction of the arrows to show the manner of supporting rollers of the window shades in the clamping plate and the adjustable mounting of the adjusting member in said plate.

Figure 5 is a fragmentary view of the lower end of the clamping plate shown at the right hand nails or screws.

side of Figures 1 and 2 with a round stud of a window shade roller positioned relative to a portion of said plate arranged for the engagement and support of said stud.

Figure 6 is a view of the opposite end portions of the adjusting member of the shade supporting means with the middle portion broken away and showing said end portions arranged for adjust able engagement with the clamping plates whereby rotation of said member in one direction actuates the plates toward each other and the rotation of the member in the opposite direction actuates the plates from each other.

In the embodiment of the invention illustrated .in the accompanying drawing, there is shown the upper part of a window frame or casement having opposed jamb members 1 arranged for the slidable mounting of a window sash 8. It is the usual practice to mount a window shade or shades between the jamb members by means of brackets having socket portions for the engagement of studs projecting from the opposite ends of a roller 9 upon which a shade I0 is mounted and rolled, one of the studs being round and fixed in one end of the roller, as shown at l I in Figure 5, and. the other stud being fiat, as shown at 12 in Figure 4, rotatably mounted in the opposite end of the roller and having a spring and dog mechanism connected thereto in the usual man-- ner, and said brackets having flanged portions extending from opposite sides of the socket portions and adapted to be permanently secured to the window jambs by suitable means, such as The use of these brackets will mar or injure the window jambs and will be diificult when the window jambs are metal.

It is the principal object of the present invention to overcome the disadvantages of these brackets by providing a pair of rectangular plates [3 and it having a peripheral flange l5 extending from one face of the plates to engage the window jambs and the opposite face having a boss extending therefrom for the engagement and supportof the window shade studs i .l and I2. In the present illustration of the invention, the plates I3 and M are arranged to support a pair of window shades, which may be of different colors or materials, and the plate It is arranged with a boss 15 adjacent each end and having an elongated opening I! in the center? thereof and a slot l8 extending from the opening at an obtuse angle thereto and opening to the periphery of the boss to permit the engagement of the fiat studs I2 in the elongated openings, as shown in Figure 3. The plate [4 is arranged with a boss l9 adjacent each end corresponding to the location of the bosses 16 in the plate |3 but having a circular opening 20 in the center thereof for the engagement and support of the round studs ll of the shade rollers 9, as shown in Figure 5. If it is desired to use only one shade ID, the plates 3 and 4 having the pairs of bosses I6 and I9, respectively, may be used with the shade roller studs engaged in either of the upper or lower bosses l6 and I9, or similar plates having only one boss at either end may be used without digressing from the invention.

The plates l3 and M are connected to each other and adapted to be actuated toward each other to permit the positioning of the plates between the jambs l and the removal of said plates from the jambs, and to be actuated from each other when said plates are positioned relative to the jambs to abut the jambs and clamp the plates against the same. This is accomplished by providing the plates I3 and I4 with bosses 2| and 22, respectively, extending from the face of each plate arranged with the bosses and I9 and between said bosses i6 and I9, and each of said bosses 2| and 22 having an inwardly extending wall 23 arranged with screw threads the screw threads in the wall 23 of the boss 2| being left handed and the screw threads in the wall 23 of the boss 22 being right handed. The screw threads in the walls 23 of the bosses 2| and 22 are engaged by corresponding screw threads 24 and 25 arranged on the opposite end portions of a rod 26 of a length slightly less than the space between the window jambs l to permit the positioning of the rod in a horizontal plane between said jambs. The screw threads 24 being left handed are engaged with the screw threads in the Wall 23 of the boss 2| and the screw threads 25 being right handed are engaged with the screw threads in the wall 23 of the boss 22, so that the turning of the rod 26 in a clock-wise direction, looking at the right hand end of the rod 26. in Figure 6, will cause the plates l3 and M to move in opposite directions toward each other out of engagement with the window jambs, as shown in Figure 1, and the rotation of the rod in the opposite or counterclock-wise direction will cause the plates to move in opposite directions away from each other into abutment with the window jambs, as shown in Figure 2. To facilitate the rotation of the rod and application of force to tightly clamp the plates against the window jambs, the rod is arranged with a series of holes 21 intermediate the ends of the rod for the releasable engagement of a suitable tool. It is to be understood that the bosses 2| and 22 may be extended from the opposed faces f the plates l6 and I9, respectively, to a greater extent than that shown in the drawing to increase the length of the wall portion 23 and thereby increase the movement of adjustment of the plates to accommodate the device for window frames of different widths.

In using two shades as shown in Figure 2, the upper shade, which is broken away in the present illustration of the invention to show the connecting and adjusting rod 26, may be extended over said rod to hide the rod from view.

Having thus described my invention, I claim:

1. In means to support window shades having studs projecting from the opposite ends thereof between the jambs of a window frame, a pair of plates having one face adapted to abut a lamb of a window frame and the opposite face arranged to engage and support a stud of a window shade and with a recess having screw threads in the wall thereof, one plate having right hand screw threads in the wall of the recess thereof and the other plate having left hand screw threads in the Wall of the recess thereof, and a rod having screw threads at the opposite ends, the screw threads at one end being right handed to engage the right hand screw threads in the recess of one plate and the screw threads at the opposite end being left handed to engage the left hand screw threads in the recess of the other plate, whereby rotation of the rod in one directicn actuates the plates away from each other into abutment with the jambs of the window I frame and the rotation of the rod in the opposite direction actuates the plates toyvard each other and out of engagement with the jambs.

2. In means to support window shades having studs projecting from the opposite ends thereof between the jambs of a window frame, a pair of plates having one face adapted to abut a jamb of a window frame and the opposite face arranged With a boss adjacent the opposite ends of each plate having an opening for the engagement of the studs of window shades and a boss intermediate the stud engaging bosses arranged with a screw threaded opening, the screw threads in the boss of one plate extending in one direction and the screw threads in the boss of the other plate extending in the opposite direction, and a rod having screw threads on the opposite end portions extending in opposite directions to engage corresponding screw threaded openings in the intermediate bosses of the plates, whereby rotation of the rod in one direction actuates the plates toward each other and out of engagement with the jambs of the window frame and rotation of the rod in the opposite direction actuates the plates from each other and into abutment with the jambs of the window frame.

3. In supporting means removably mounted in a frame opening, a pair of plates, each plate having one face adapted to abut an opposed jamb of a frame opening and the opposite face arranged with a boss having a screw threaded opening therein, the screw threads in the boss of one plate extending in one direction and the screw threads in the boss of the other plate extending in the opposite direction, and a rod having screw threads on opposite end portions extending in opposite directions, the screw threads on each end portion of the rod adapted to engage the corresponding screw threaded opening in the boss of a plate, whereby rotation of the rod in one direction actuates the plates toward each other and out of engagement with the opposed jambs of the frame opening and rotation of the rod in the opposite direction actuates the plates away from each other and into abutment with the jambs of the frame opening to support the rod between said opposed jambs.
